cells, this is the reason why the antibiotic can differentiate between the good guys
and the bad guys. |

| what are bacteriostatic antibiotics? |
|
Definition
| baceriostatic antibiotics inhibit groth and reproduction of bacteria without killing them. Bacterioststic antibiotics have to work with the immune system to remove the pathogenic microoganisms from the host. Bacteriostatic antibiotics limit the groth of bacteria by interfering with pacterial protein production or by interfering woith the bacterial microorganism. |

| what are the dangours of antibiotic resistance |
|
Definition
1- Infections caused by resistant microorganisms often fail to respond to the standard treatment, resulting in prolonged illness and greater risk of death.
2- When infections become resistant to first-line medicines, more expensive therapies must be used. The longer duration of illness and treatment, often in hospitals, increases health-care costs and the financial burden to families and societies.
3- The achievements of modern medicine are put at risk by antibiotic resistant microorganisms. Without effective antbiotics for care and prevention of infections, the success of treatments such as organ transplantation, cancer chemotherapy and major surgery would be compromised.
4- The growth of global trade and travel allows resistant microorganisms to be spread rapidly to distant countries and continents |

Definition
| Probiotics are live microorganisms thought to be beneficial to the host organism. According to the currently adopted definition by FAO/WHO, probiotics are: "Live microorganisms which when administered in adequate amounts confer a health benefit on the host".[1] Lactic acid bacteria (LAB) and bifidobacteria are the most common types of microbes used as probiotics; but certain yeasts and bacilli may also be helpful. Probiotics are commonly consumed as part of fermented foods with specially added active live cultures; such as in yogurt, soy yogurt, or as dietary supplements. |
